Directory traversal vulnerability in X-Diesel Unreal Commander 0.92 build 565 and 573 allows remote FTP servers to create or overwrite arbitrary files via a .. (dot dot) in a filename. NOTE: this can be leveraged for code execution by writing to a Startup folder.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
